--> $DIR/invalid-bin-op.rs:2:15

LL | let _ = s == t;

| S<T>

note: an implementation of `PartialEq<_>` might be missing for `S<T>`
--> $DIR/invalid-bin-op.rs:5:1

LL | struct S<T>(T);
| ^^^^^^^^^^^ must implement `PartialEq<_>`
help: consider annotating `S<T>` with `#[derive(PartialEq)]`

LL + #[derive(PartialEq)]
LL | struct S<T>(T);

help: consider introducing a `where` clause, but there might be an alternative better way to express this requirement
